[0044] The following is combined with Figure 1-8 This application is described in further detail.

[0045] The embodiment of the present application discloses a buckle strip 1, which is installed on a backrest to facilitate connection with an elastic member 2. Specifically, the buckle strip 1 includes a connecting portion 11 and a hanging portion 12, the hanging portion 12 is used to connect the elastic member 2, and the connecting portion 11 is convenient for installation on the backrest to facilitate connection between the buckle strip 1 and the backrest. The buckle strip 1 specifically discloses the following embodiments:

[0046] Embodiment 1

[0047] As attached Figure 1 As shown, a hanging portion 12 is provided on the connecting portion 11, and the length of the buckle strip 1 can be cut according to the installation requirements. In this embodiment, the cross section of the buckle strip 1 along the length direction is "J" shaped as a whole, wherein: the connecting portion 11 is a "J" shaped transverse section, and the hanging portion 12 is a "J" shaped longitudinal bending section. Such a design enables the buckle strip 1 to be connected to the backrest by plugging through the connecting portion 11, making the installation of the buckle strip 1 more convenient and quick, and only a slot needs to be preset on the backrest, while the hook member in the prior art needs to be fastened and installed with screws, which is more troublesome.

[0048] In other embodiments, the connecting portion 11 may also be in other shapes such as a cylinder for easy insertion.

[0049] The hanging portion 12 is provided with a through hole 13, which is opened through the length direction of the connecting portion 11. The elastic member 2 can be connected to the hanging portion 12 by passing through the through hole 13. The installation of the elastic member 2 and the buckle strip 1 is simple and convenient, and the design of the through hole 13 can ensure the reliability of the connection between the elastic member 2 and the buckle strip 1, that is, except for the axial direction of the through hole 13, the elastic member 2 cannot be separated from the hanging portion 12 in other directions. In this embodiment, the elastic member 2 adopts a serpentine spring.

[0050] In this embodiment, the end of the elastic member 2 is passed through the through hole 13 and connected to the hanging portion 12. The end of the elastic member 2 generally has a certain plasticity. After the end of the elastic member 2 is passed through the through hole 13, the end of the elastic member 2 can be bent, so that the elastic member 2 cannot be separated from the hanging portion 12 along the axial direction of the through hole 13, thereby ensuring the reliability of the connection between the elastic member 2 and the buckle strip 1.

[0051] In a further configuration, the through hole 13 has a margin for the elastic member 2 to move along the length direction of the perpendicular connecting portion 11. Specifically, the end of the elastic member 2 is connected with the through hole 13 and the through hole 13 is opened along the length direction of the connecting portion 11, so the tension direction of the elastic member 2 is perpendicular to the length direction of the connecting portion 11, and the end of the elastic member 2 has a tendency to move relative to the hanging portion 12 during the stretching process. The through hole 13 has a margin to enable the end of the elastic member 2 to move relative to the hanging portion 12, so as to improve the adaptability of the elastic member 2 to be connected to the hanging portion 12 during use.

[0052] In this embodiment, the through hole 13 is a bar-shaped hole with a bar-shaped cross section. Of course, the shape of the through hole 13 is not limited to the above-mentioned bar-shaped hole, and the cross section may also be an elliptical, rectangular, etc., that is, the length of the through hole 13 along the length direction of the vertical connection part 11 needs to be larger than the diameter of the steel wire of the elastic member 2.

[0053] It should be noted that when the elastic member 2 is a composite elastic member 2 composed of two or more elastic members 2 , the length of the through hole 13 along the length direction of the vertical connection portion 11 needs to be larger than the diameter of the steel wire of the composite elastic member 2 .

[0054] In addition, in this embodiment, the entire buckle strip 1 can be produced by extrusion molding to facilitate punching of the buckle strip 1, that is, the connecting portion 11 and the hanging portion 12 are extruded integrally. In other embodiments, the connecting portion 11 and the hanging portion 12 can also be two separate parts assembled into the buckle strip 1 by welding, bolting, etc.

[0055] Embodiment 2

[0056] As attached Figure 2 , Attachment Figure 3 As shown, the difference from the first embodiment is that the number of the hanging parts 12 on the connecting part 11 is more than two, and the hanging parts 12 are distributed along the length direction of the connecting part 11.

[0057] In this embodiment, five hooking parts 12 are arranged along the length direction of the connecting part 11, that is, a maximum of five elastic members 2 can be connected to the same buckle strip 1, and only one installation operation is required when the buckle strip 1 is installed on the backrest, which is simple, convenient and fast to install. In the existing installation of hooks, the number of elastic members 2 corresponds to the number of hooks, and the number of hook installations is large. Therefore, the more the number of elastic members 2 required to be installed, the higher the installation efficiency of the method of connecting the elastic members 2 with the buckle strip 1.

[0058] Compared with the first embodiment, the present embodiment has more hanging parts 12. When there are more than two hanging parts 12, the buckle strip 1 is punched along the length direction of the vertical connecting part 11 to obtain more than two connecting parts 11. Based on user needs and the installation requirements of the elastic part 2, the number of hanging parts 12 on the buckle strip 1, the position of the hanging parts 12 and the thickness of the hanging parts 12 along the length direction of the connecting part 11 can be customized.

[0059] In this embodiment, only the hanging portion 12 is punched along the length direction of the vertical connecting portion 11. Figure 2 B is a partial enlarged view, Figure 2 B' in the figure is a punching schematic diagram, and the arrow in B' is the punching direction.

[0060] Embodiment 3

[0061] As attached Figure 4 , Attachment Figure 5 As shown, the difference from the second embodiment is that the hanging part 12 and the connecting part 11 are partially punched along the length direction of the vertical connecting part 11. Figure 4 C in the figure is a local enlarged view. Figure 4 C' in the figure is a punching diagram, and the arrow in C' is the punching direction.

[0062] Embodiment 4

[0063] As attached Figure 6 , Attachment Figure 7 As shown, the difference from the second embodiment is that a through slot 14 is formed on the hanging portion 12 along the length direction of the connecting portion 11, and a stopper 15 is provided at the buckle of the through slot 14 to prevent the elastic member 2 from being separated from the notch side of the through slot 14, and there is a margin between the stopper 15 and the bottom of the through slot 14 for the elastic member 2 to move along the depth direction of the through slot 14. Figure 6 D in the figure is a local enlarged view. Figure 6 D' in the figure is a punching diagram, and the arrow in D' is the punching direction.

[0064] Compared with the second embodiment, the elastic member 2 in this embodiment can be directly hooked onto the through slot 14 , which makes installation more convenient and quick. The provision of the anti-detachment portion 15 can ensure the reliability of the connection between the elastic member 2 and the buckle strip 1 .

[0065] In this embodiment, the anti-slip portion 15 is an arc-shaped protrusion and protrudes toward the inner bottom of the through groove 14. In addition, the buckle strip 1 is extruded and has a certain elasticity. When the elastic member 2 is hooked into the through groove 14, the side wall of the through groove 14 is pushed to expand outward so that the elastic member 2 can be hooked into the through groove 14. After the hooking is completed, the side wall of the through groove 14 is elastically restored. Since the anti-slip portion 15 protrudes toward the inner bottom of the through groove 14, it has a blocking and anti-slip effect on the elastic member 12.

[0066] The present application also discloses a backrest, as shown in the attached Figure 8 As shown, it includes two mounting parts 3, more than two mounting beams 4, an elastic part 2 and a back plate 5. The mounting beam 4 is fixed between the two mounting parts 3. A buckle strip 1 is fixedly connected to the mounting beam 4 and is fixedly connected to the connecting part 11 of the buckle strip 1. The elastic part 2 is connected between the buckle strips 1 on the two mounting beams 4, and the back plate 5 is installed between the two mounting beams 4.

[0067] In this embodiment, the two mounting members 3 are distributed on the left and right, and the distance between the two mounting members 3 is the width of the backrest. Three mounting beams 4, namely, upper, middle and lower, are fixedly connected between the two mounting members 3, wherein the upper mounting beam 4 is the first mounting beam 41, the middle mounting beam 4 is the second mounting beam 42, and the lower mounting beam 4 is the third mounting beam 43. The back panel 5 is installed and connected between the first mounting beam 41 and the second mounting beam 42. Slots (not shown) for inserting the connecting portion 11 of the buckle strip 1 are provided on the first mounting beam 41 and the third mounting beam 43 for installing the buckle strip 1. The elastic member 2 is connected between the upper and lower buckle strips 1, and a plurality of elastic members 2 are distributed along the left and right directions.

[0068] It should be noted that, when only one elastic member 2 is provided, the buckle strip 1 connected to the first mounting beam 41 may adopt any one of embodiments one to four, and the buckle strip 1 connected to the second mounting beam 42 may also adopt any one of embodiments one to four; when more than two elastic members 2 are provided, the buckle strip 1 connected to the first mounting beam 41 may adopt any one of embodiments two to four, and the buckle strip 1 connected to the second mounting beam 42 may also adopt any one of embodiments two to four.

[0069] In addition, the number of the hanging portions 12 on the buckle strip 1 corresponds to the number of the elastic members 2 , and the elastic members 2 are connected to the corresponding hanging portions 12 of the upper and lower buckle strips 1 to avoid the elastic members 2 from crossing.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
